Procedure
Wet Pipe Systems: Use Model CPRTK-4
(With older-style ceiling mount, not Riser Mount (RM) style.)
1. Turn the two 1" ball valves (PCMS) or butterfly valve (PCMS-LP)
to closed position to isolate the coupon rack from the fire sprinkler
system.
2. Verify that the 1/2" drain valve is in the closed position.

3. Relieve system pressure from the coupon rack by opening the
drain valve slowly. Do not drain the coupon rack completely at
this time. Use a container or bucket to catch the escaping water.

Carefully read and follow the instructions and procedures provided
in this and referenced documents. Failure to do so will inhibit the
ability to provide accurate and complete test results.
Do not handle the coupons or probes with your bare hands. Use the
latex gloves provided.
The CPRTK contains necessary components to remove, replace, and
forward for analysis, the test coupons and water sample from a Potter
Corrosion Monitoring Station.
Test Kit Includes:
• Two C1010 Mild Steel Corrosion Coupons
(One for CPRTK-2)
• Two Corrosion Monitoring Probes (One for CPRTK-2)
• Two CDA 360 Non-Ferrous Brass Coupons (One for CPRTK-2)
• Corrosion Coupon Insertion Confirmation Sheet
NOTE: The water in the coupon rack will be pressurized to the
system pressure. After the system pressure has been relieved,
close the drain valve.
4. Fill the 120cc bottle by opening the drain valve slowly. Close the
1/2" drain valve.
5. Securely affix the cap to the bottle by making sure the cap screws
on tightly. Tape cap to bottle.
6.Drain the remaining water from the coupon rack through the 1/2"
drain valve into a container. Close the 1/2" drain valve. Re-install
the 1/2" plug into drain valve.
7. Locate the plastic document holder (should be attached to the
monitoring station). Locate the completed coupon insertion
confirmation sheet and original coupon envelopes. Find the
coupon envelope that corresponds with Outlet #1.
8.Remove the coupon holder from Outlet #1. Use a screwdriver
to loosen the plastic screw and nut. (See Fig. 1) Remove the
coupon from the coupon holder and place the coupon into the
corresponding original coupon envelope. Repeat this process on
outlet #5. (See Fig. 3)
DO NOT HANDLE COUPONS OR PROBES WITH BARE
HANDS.
9. Notify the fire system administrator to disable the fire panel
zone connected to the corrosion monitoring probe. Remove the
pressure switches from the corrosion monitoring probes on outlet
#3 and #6 (See Fig. 3). If a union was used between the pressure
switch and the corrosion monitoring probe you will not have to
disconnect the wiring to the pressure switch. Remove corrosion
monitoring probes from outlet #3 and #6 and discard.
Tools Required:
10.Remove the corrosion monitoring probe from the sealed
packaging using the latex gloves provided. Carefully remove the
protective cardboard sleeve. Apply Teflon tape to the 1” NPT male
pipe threads and install the new probe in the same outlet the old
probe was removed from.
• Pipe wrench or 14" adjustable wrench to remove and replace
coupon holders and probes.
11.Remove the new corresponding coupon from the new coupon
envelope. Do NOT discard the envelope.
• 120cc Bottle with Cap (Used for Wet Pipe Systems Only)
• One Pair of Latex Gloves
• Container used to drain water from the isolated coupon rack.
• Phillips head screwdriver to remove and re-install coupons to the
coupon holders.
• Teflon tape
• Ferrous/mild steel locations are for C1010 coupons.
• Non-Ferrous/Brass locations are for CDA 360 coupons.
12.Confirm the serial numbers on the envelope and coupon match.
